SHEET-METAL-LQLYOUT TOOL;

Appliqation filed Aprili15, 19%.; Serial No. 102,355.-

lhis invention relates to tools for laying out the bends or folds to be made in a sheet of. metal, in the formation of'mold ngs, cornices and various other sheet metal articles,

trimmings and the like; and the object of the invention is toprovide a tool of theclass described which is so constructed as to. facili-" tate the quick layont of predetermined dimensions and markings on a workpiece. and especially in the J tern, shape or form. in a multipl city of workpieces whereby the time required in the marking of Workpiecesis reduced to a minimum; a. still further object being to provide a: device of the class specified which, is movably mounted in connection with a work bench whereby the same may be moved into operative. and inoperative positions; 'a fur-' ther object being to. provide a tool: of the class described, thevface of which. is provided with, a plurality of staggeredly arranged apertures adaptedv to. receive. a predetermined number of; pointed devices whereby the markings or layouts may be made one workpiece and accurately arranged with n comparatively smalldimensions; and, with these and. other objects in View, the invention consists in a device of the class and V for the purpose specified. which is simple in construction, efiicient in use and: which is constructed, as hereinafter described and claimed.

Fi 6 is a sectional detail view of a modified orm of constru ction which I employ.

In the drawing 10 represents a. table, or

work-bench of any kind or class and at 11 I have, indicated a hinge bracket secured to one, side edge of V the Work-bench and to which my improved layout tool 12 is pivot ally mounted as seen at'1'3. The tool; 12 is of channel formation in, cross section and in v use, the. channel is directed downwardly and, the upper. fiat faceis providedgwith a plurality of staggeredly arranged apertures 142 which in the construction shown in Figs. 1, 2 and 3 of the drawin I vare threaded to receive. one of a number- 0 pointed pegs 1,5, the pointsl fiof which project through, the top faceof the tool,1 2.' 7 l p It will bev noted that the apertures are. arranged in diagonal, rows transversely of.

the top face of. the tool, the apertures of one row are in spaced arrangement and when, viewed, transversely of the tool. as clearly seen in Fig. l of the drawing.

The side portionsofthe tool are provided at the upper face thereof with projecting flanges; 17 whereby agage 1'8'having hookshaped ends 19 may be conpledwith'the tool and moved longitudinally thereof and re taineol, in different positions of adjustment by a, set screw 20. The gage, 18 serves as a iuare placed in, the. use of the tool, the workpiece 21 being inthe form of a sheet of metal ,which may be of, any desired length but preferably of predetermined width.

In Fig; 6 of the drawing, Lhave shown a M slight modifieation wherein I have substiis. a view similar to Fig. 1,, but

tutedi for the screw pegs- 15',- ta-pered pegs22 which are, adapted to seat in countersunk ends 25 projecting slightly topermi-tof the removal of the pegs 22 by ta-ppingthe same th a harem/ever n. a y ethe d ir m ner, The construction shownin Fig. 6; will fa l a heq ar att m nt; nd: e ac edge against: which a workpiece 21; is-

intermediate the apertures of adjacent rows ment of the pegs. It will be understood that either form of construction may be employed.

It will be understood that the apertures 14- and 23 extend from one end of the tool to the other, only a few of the apertures being shown to simplify the illustration. In Figs. 1 and 2 of the drawing, I have shown an arrangement of the pegs 15 in the tool to produce the finished product 26 seen in Fig. 4 of the drawing from the workpiece 21 or from a. strip of metal of predetermined width and of indefinite length. It will be understood that the gage 18 is first adjusted to the desired position on the tool 12 to bring one of the apertures 14 in the tool, such distance from the edge of the gage that when a peg 15 is inserted in said aperture as seen at at, Fig. 1, the first marking i on the workpiece will be formed, which marking will indicate the first bends 26 to be formed in the resulting product. Another peg is inserted into another aperture as at m to form the second marking 7 and the second bend 26" note Figs. 1, t and 5, and other pegs designated at 00 m and m are arranged on the .workpiece to provide markings 7 to 7 inclusive on the workpiece to produce the remainder of the bends formed in the finished product seen in Fig. 4 of the drawing. The dotted lines in Fig. 5 of the drawing indicate the bends or fold lines, but it will be understood that all that is applied to the sheet or workpiece 2]. are a series of fine punched holes or impressions, and these markings may be arranged at one place only on the sheet or atspaced intervals if desired.

According to the present procedure, it is customary to lay out a templet or pattern piece and with the use of this pattern piece and a punch or pointed tool, the workman stamps by hand each and every marking designated by the templet or pattern piece, and this operation is repeated over and over again in the production of a multiplicity of similar workpieces. lVith my improved construction, after a desired arrangement of the pegs has been produced in the tool and the gage 18 fixed in proper position, all that is necessary for the workman to do is to lay a sheet or workpiece upon the tool with one edge thereof abutting the gage 18, and by the use of a hammer or other tool, the workpiece is tapped or struck longitudinally of the tool preferably acent the arrangement of pegs thereon to form the markings z to ;1 therein. In this way, the desired result is accomplished in aquick and accurate man ner, it being borne in mind that all of the workpicceswill be correspondingly and accurately marked. i

It will be understood that my invention is notlimited for use in workpieces of the class indicated in the drawing, nor is my improved tool necessarily limited to the specific use herein described, and various changes in and n'lodifications ot' the construction herein set out may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.

In Fig. 1 of the drawing I have shown a slight modification of the arrangement of the apertures in the top face of the tool where the apertures 14 are arranged in angular rows 26 and 27 in such manner that the apertures in one row 27 are intermediate the apertures of adjacent rows' 26 when viewed transversely or at right angles to the longitudinal plane of the tool, thus providing a. closer spacingof the apertures as will be apparent.
